at the same time, my, my recollections going back to these fisa debates is that we were somehow limiting surveillance to foreign calls or calls between a foreign source and a domestic source, this does not involve surveillance. this is just a collection of the numbers. so that once you get actionable intelligence and go to a court and review it with the intelligence committees, you can go back into these computers and see whether a call was with a made to one of these numbers, so that the numbers are kept. because otherwise the phone companies don't keep the numbers for more than 30 to 90 days. is this the case, though, that the numbers would involve domestic numbers, not just foreign numbers? >> yes the people, foreign numbers are calling domestic numbers, yes. and then if, if that person is under suspicion, they can also look at the numbers that the domestic person is called. and my understanding is, if they want to look at content, they have to go into a court.
